Answer:

The answer is: A. Hope it helps.

By evaluating the function graphically ,  f (4) = -4

An expression, rule, or law in mathematics that establishes the relationship between an independent variable and a dependent variable (the dependent variable).

The x-axis is indicated with the input values. The vertical displacement from the x-axis is the appropriate output value for any input value. For instance, the output is identical to f when x = a. (a).

According to the Given information

f( x ) = y

where x is an input and y is an output

We need to find the value for f(4)

f( 4 ) = y

For x = 4 we have a corresponding value at y axis as -4 in fourth quadrant

Step-by-step explanation:

The vertex of the parabola is at (0.5, 8.5).

The percentage of all customers prefer port drink and tea is 17.55%. The result is obtained by multiplying the two percentages of the data.

We have a number of customers.

Of all customers, find the percentage that they prefer port drink and tea!

If 55% prefer soda over port drink, then the ones who prefer port drink is

100% - 55% = 45%

Of the customers who prefer port drink, 61% prefer coffee over tea. So, the ones who prefer tea is

100% - 61% = 39%

From that information, we can get the ones who prefer port drink and tea. Let's say pt = port drink and tea.

pt = 39% × 45%

pt = 0.39 × 0.45

pt = 0.1755

pt = 17.55%

Hence, of all customers, the percentage who prefer port drink and tea is 17.55%.

the solution to the equation is x=12

The distributive property is defined as

Let us now solve the equation.

5(x - 6) = 2(x + 3)

Using the distributive property, simplify the parentheses on both sides.

5(x - 6) = 2(x + 3)

5x - 30 = 2x + 6

The parenthesis was simplified. However, we have one x term on one side and another x term on the other.

5x - 30 - 2x = 2x + 6 - 2x

3x - 30 = 6

We only have an x term on one side of the equation now.

To begin, reverse the subtraction by adding 30 to either side of the equation.

To keep an equation balanced or true, we do the identical operation on both sides.

3x - 30 + 30 = 6 + 30

3x = 36

We're getting close to an answer. Only one more step.

The x term is multiplied by 3.

We can undo the multiplication operation by dividing both sides by 3.

3x / 3 = 36 / 3

x = 12

So, x is equal to 12.

f(x) = Area = (length)(width)

width = x

The length is 16 yards greater than 3 times x

length = 3x+16

f(x) = (3x+16)(x) = 3x^2 + 16x

Answer:

Step-by-step explanation:

We have been given that -- The length of a rectangular parking lot is 16 yards greater than 3 times its width, x, in yards

Length of parking lot is 16 + 3x

Width of parking lot is x

We have to write the function f(x) that describes the area, in square yards, as a function of the width, x

Area of rectangle is Length × width

[tex] \sf Area = f(x) [/tex]

put value of length and width here,

The whole numbers are closed under subtraction only by distributive property else they are not closed under subtraction.

Whole numbers constitute natural numbers including zero. The subset is given by {0, 1, 2, 3, 4, 5, …}, the set does not include fractions, decimals, and negative integers. The set of whole numbers is represented by ‘W’={0, 1, 2, 3, 4, 5, …...}

To check if the whole numbers are closed under subtraction or not we will check out the four properties namely, the closure property, the commutative property, the associative property, and the distributive property.

Let us consider each property one by one -

1. The closure property-

let's take two whole numbers say 5 and 2.

now 5-2=3, but 2-5= -3 which is not a whole number.

Thus, whole numbers are not closed under subtraction by closure property.

2. The commutative property-

let's take two whole numbers say 5 and 2.

now 5-2=3 and 2-5=-3

hence, we get 2-5 ≠ 5-2.

Thus, whole numbers are not closed under subtraction by commutative property.

3. The associative property-

let's take three whole numbers say 5, 3, and 2.

now (5-3)-2 = 0 and 5-(3-2)= 4

hence, we get (5-3)-2 ≠ 5-(3-2).

Thus, whole numbers are not closed under subtraction by associative property.

4. The distributive property-

let's take three whole numbers say 20, 6, and 5.

now, 20 × ( 6 – 5 ) =  20 × 6 – 20 × 5  = 20

         and 20 × ( 6 – 5 ) = 20 × 1 = 20

Hence, 20=20.

Thus, whole numbers are closed under subtraction only by distributive property.

Hence, we can conclude that whole numbers are closed under subtraction only by distributive property.

The equation of line r which is parallel to line q and passes through point (5,-4) is y = (-3/5)x - 1.

The slope-intercept form is expressed as;

y  = mx + b

The point-slope formula is expressed as

y - y₁ = m( x - x₁ )

Given the data in the question;

First, determine the slope of the line q using the slope intercept-form.

y = mx + b

3x + 5y = 10

5y = -3x + 10

y = (-3/5)x + 10/5

y = (-3/5)x + 2

Hence;

Slope of line q m = -3/5

Since, line r is parallel to line q, they both have the same slope.

Therefore, slope of line r will be m  = -3/5

Now, plug the point  (5,-4) and and slope m = -3/5 into the point slope formula and solve for y.

y - y₁ = m( x - x₁ )

y - (-4) = (-3/5)( x - 5 )

y + 4 = (-3/5)x + 3

y = (-3/5)x + 3 - 4

y = (-3/5)x - 1

Therefore, the equation of line r is  y = (-3/5)x - 1.

The given function is  x² - 7x + 5 and the most general antiderivative of the function  is F(x) = x³/3 - 7x²/2 + 5x + c.

The antiderivative of a function (also called the integration of a function) is the reverse of the differentiation of that function. Given a function f(x), its integration, F(x), can be calculated as follows;

F(x) = ∫f(x)dx

From the question, f(x) = x² - 7x + 5

Therefore,

F(x) = ∫x² - 7x + 5

F(x) = x³/3 - 7x²/2 + 5x + c

Where c is the constant of the integration (antiderivative).

The constant of integration is used for indefinite integrals and allows to express integration of a function in its most general form.

Therefore,  F(x) = x³/3 - 7x²/2 + 5x + c is the most general antiderivative of the function.

Answer:

Step-by-step explanation:

Any degree-X polynomial can have up to 8 zeros (some of them can have multiciplity higher than 1).

The polynomial can be written as:

f(x) = (x-a)(x-b)(x-c)(x-d)(x-e)(x-f)(x-g)(x-h)

and we're already told that there are 2 x-intercepts, one with multiplicity 1. Let's assign those x-intercepts a and b=c=d (multiplicity 3).

We're left with (x-e)(x-f)(x-g)(x-h), where e, f, g and h need to be non-real complex numbers (otherwise they'd provide x-intercepts).

The complex zeros (more accurate term than imaginary) must come in pairs - if a number c is a zero of the function, its conjugate is a zero too. That means that we need to have an even number of complex zeros.

We can either have 4 distinct complex zeros, or 2 complex zeros, each with multiplicity of 2.

The function x^2 +10x +15 in vertex form is (x+5)^2 - 10 and the vertex is a minimum at (-5, -10)

The vertex of a parabola is a point at which the parabola makes its sharpest turn. A parabolic function has either a maximum value (if it is of the shape '∩') or a minimum value (if it is of the shape 'U"). The vertex of a parabola is also the point of intersection of the parabola and its axis of symmetry.

y = x^2 + 10x +15

making x^2 + 10x +15 a perfect square expression we square the half of the coefficient of x on both sides which is (5)^2

y + (5)^2 = x^2 + 10x + (5)^2 + 15

y + 25 = x^2 + 10x + (5)^2 + 15

x^2 + 10x + (5)^2  can be written as (x+5)^2 since iti is now a perfect square expression

y + 25 = (x+5)^2 + 15

y = (x+5)^2 + 15 - 25

y = (x+5)^2 -10

Equation of parabola in vertex form is  y = a (x - h)2 + k

where k is the minimum or maximum point of vertex and h is the x coordinate of vertex.

comparing both equations, the coordinate of vertex (h, k) is (-5, -10) which is a minimum point.

In conclusion the vertex is a minimum at (-5, -10) and the equation in vertex form is  (x+5)^2 -10

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes.

What is a triangle?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

Given that the vertices of △JKL are J(1, 0), K(-5, 2), L(4, -4).

The vertices of △J'K'L' are J'(-9, 0), K'(-3, 2), L'(-12, -4).

The formula of midpoint of (x₁, y₁) and (x₂, y₂) is

((x₁+x₂)/2,  (y₁+y₂)/2)

The midpoint of J(1, 0) and J'(-9, 0) is ((1+(-9)/2,(0+0)/2) = (-8/2,0) = (-4,0)

The midpoint of K(-5, 2) and K'(-3, 2) is ((-5+(-3)/2,(2+2)/2) = (-8/2,4/2) = (-4,2)

The midpoint of L(4, -4) and L'(-12, -4) is ((4+(-12)/2,(-4+(-4))/2) = (-8/2,-8/2) = (-4,-4)

Thus the x-coordinate of the midpoint is the same.
